[EnergyPlus_Support] Re: No gas consumption on Boiler

["stefan_thor_smith" <stsmith@xxxxxxxxx>]

Thanks Richard,

The eio file reports a none zero value for the boiler nominal capacity and the temperature 
profile of the zone suggests it is still being heated.

As a Mac user I'm waiting for V3 to be made available.

Regards,
Stefan
